Under  the  above  title,  for  the  purpose  of  citation  easily 
abbreviated  to  PL  Baker.,  it  is  proposed  to  issue  a  series  of 
lists  of  plants  collected  by  Mr.  Carl  F.  Baker  and  his  col- 
leagues and  distributed  to  various  herbaria  on  both  sides  of 
^  the  Atlantic. 

vs       The    first   volume   of    these    Catalogues    will     include 

the   collections   of    1898   by   Messrs.    C.   F.   Baker,  F.    S. 

>i  Earle  and  S.  M.  Tracy  in  Southern  Colorado.     The   sets

NARRATIVE. 

By  F.  S.  EARLE. 

In  planning  a  botanical  collecting  trip  to  Southwestern 
Colorado  our  objects  were  first,  to  secure  sets  of  plants  rep- 
resentative of  the  flora  of  this  interesting  region ;  and, 
second,  to  study  in  the  field  the  effect  of  altitude  and 
exposure  on  the  variability  and  the  distribution  of  species. 
It  was  at  first  hoped  that  we  might  be  able  to  examine  some- 
what critically  the  La  Plata  Mountains  in  the  extreme  South- 
western part  of  the  State,  and  also  considerable  portions 
of  the  larger  neighboring  range  of  the  San  Juan.  Lack 
of  time  prevented  carrying  out  the  latter  plan,  the  work 
being  confined  exclusively  to  the  La  Plata  Range,  and 
the  neighboring  lower  levels.  The  region  proved  ad- 
mirably adapted  to  the  purposes  of  the  expedition.  The 
Range  is  isolated,  and  though  small  in  area  is  of  consider- 
able altitude,  the  central  peak,  Mt.  Hesperus,  holding  its 
rugged  snow-streaked  crest  at  the  height  of  13,300  feet.  As 
seen  from  the  west  this  mountain  presents  a  peculiar  and 
fantastic  appearance.  The  portion  above  timber  line  is  a 
regularly  outlined  rock  pyramid  formed  of  nearly  horizontal 
strata  of  various  colors  giving  a  curious  banded  effect ;  while 
numerous  gulches  filled  with  snow  mark  it  with  vertical 
lines  of  white.  Mt.  Hesperus  is  flanked  and  supported  on 
the  North  by  Shark's  Tooth,  a  pinnacle  of  rock  well  deserv- 
ing its  name  ;  on  the  South  by  the  jagged  double  peak  of 
Mt.  Moss,  or  Mt.  Hayden  as  it  is  locally  called,  and  on  the 
East  by  Snowstorm  Peak,  which  justified  its  cognomen  dur- 
ing our  stay  in  its  neighborhood  by  covering  itself  with  a 
fresh  coat  of  white  in  the  middle  of  July.  None  of  these 


2  PLANTS    BAKERIAN^E. 

outlying  peaks  rival  the  central  mass  of  Mt.  Hesperus, 
but  all  reach  nearly  or  quite  13,000  feet,  and  their  sheltered 
gulches  hold  abundant  snow  far  into  the  summer  to  feed 
the  mountain  brooks,  and  furnish  moisture  for  the  luxuri- 
ant alpine  vegetation  that  springs  up  like  magic  as  the 
snow  line  retreats.  From  the  basins  between  these  peaks 
arise  many  streams.  The  La  Plata  River  rises  to  the  east- 
ward of  Hesperus  and  flows  nearly  due  South ;  East, 
Middle,  and  West  Mancos  creeks  flow  from  its  western 
flanks,  all  uniting  above  the  town  of  the  same  name  to 
form  the  Mancos  River,  which  flows  in  a  southwesterly 
direction.  Bear  Creek  rising  North  of  Hesperus,  between 
that  peak  and  Shark's  Tooth,  flows  to  the  northwestward, 
while  the  drainage  from  the  eastern  side  of  Shark's  Tooth 
and  Snowstorm  Peak  and  is  tributary  to  the  Las  Animas. 

Two  of  our  party  reached  the  little  town  of  Mancos  on 
the  Rio  Grande  Southern  railway  on  Tuesday,  June  21, 
1898,  and  went  into  camp  near  the  river  to  await  the  com- 
ing of  the  third  member  who  had  been  detained  at  his 
home  in  Mississippi  by  a  suddenly-imposed  yellow  fever 
quarantine. 

The  valley  at  Mancos  is  from  one  to  two  miles  wide.  For- 
merly a  sage  plain,  it  is  now,  thanks  to  irrigation,  mostly 
covered  with  green  wheat  and  alfalfa  fields.  Owing  to  its 
elevation.  7,000  feet,  corn  and  the  more  tender  vegetables 
can  not  be  grown  on  the  Mancos.  To  the  North  and  East 
the  valley  is  bounded  by  the  foot  hills  and  lower  ridges  of 
the  La  Plata  Range,  the  snow-streaked  top  of  Hesperus 
being  plainly  visible.  The  hills  bounding  the  valley  to 
the  South  are  strikingly  different  from  these  in  conforma- 
tion, being  flat-topped  with  precipitous  sides,  evidently 
belonging  to  the  great  mesa  formation  of  the  Southwest. 
The  steep  northern  slopes  of  these  mesas  facing  the  valley 


NARRATIVE.  3 

are  covered  by  a  dense  growth  of  chaparral,  giving  them  in 
the  distance  a  deep  blue  or  almost  black  effect.  This  cha- 
parral consists  largely  of  scrub  oak  Quercus  undulata  inter- 
spersed or  sometimes  almost  replaced  by  clumps  of  Ame- 
lanchier,  Peraphyllum,  Rhus,  Fendlera,  and  Cercocar- 
pus.  The  summits  of  the  lower  foot  hills  on  either  side  of 
the  valley  support  a  scattered  growth  of  nut  pine  and  red 
cedar,  Pinus  edulis  and  Juniperus  monosperma.  Looking  west- 
ward the  eye  wanders  over  great  stretches  of  undulating 
sage  plains  and  piiion-covered  ridges  to  the  Blue  Mountains 
of  Utah  a  hundred  miles  away.  Southwestward  the  view 
is  limited  by  the  less  elevated  Ute  Mountain  Range,  lying 
distant  some  thirty  miles. 

The  five  days  of  a  necessary  detention  at  Mancos  were 
devoted  to  the  flora  of  the  valley ;  and  '  these  proved  quite 
as  instructive  as  any  equal  portion  of  time  spent  at  higher 
altitudes.  Three  well-defined  floral  belts  were  reached  from 
this  riverside  camp.  First,  the  flood  plain  of  the  Mancos,  a 
narrow  bottom,  varying  from  a  few  yards  to  a  quarter  of  a 
mile  in  width.  Some  parts  of  it  are  grassy  and  meadow- 
like  ;  others  occupied  by  swampy  thicket.  The  largest  trees 
are  those  of  the  narrow-leaved  poplar,  Populus  angustifolia ; 
and  this  was  the  only  member  of  its  genus  seen  here, 
except  the  aspen.  The  buffalo  berry,  Lepargyrea  argentea, 
conspicuous  by  its  silver-gray  foliage,  is  abundant,  forming 
large  clumps,  and  reaching  the  height  of  fifteen  and  even 
twenty  feet.  The  thickets  are  composed  of  various  willows, 
interspersed  with  some  choke-cherry  trees,  Cerasus  demised, 
and  dogwoods,  Cornus  stolonifera  ;  these  supplemented  by 
dense  masses  of  Distegia  involucrata  reminding  one  of  the 
hedges  of  so-called  "buckbrush,"  Cephalanthus,  bordering 
the  banks  of  swampy  lakes  in  Mississippi  River  bottoms. 

At  this  elevation  the  Distegia  (the  Lonicera  involucrata  of 


4  PLANTS    BAKERIASLE. 

some  authors)  attains  the  height  of  eight  or  ten  feet;  but  up 
near  the  timber-line  it  is  a  dwarf  of  sometimes  not  more 
than  one  or  two  feet.  The  more  conspicuous  herbaceous 
plants  of  these  thickets  are  Mertensia  ciliata,  Geranium  Rich- 
ardsonii,  a  new  species  of  buttercup,  Ranunculus  Earlei 
(Greene),  and  Polemonlum  filicinum,  a  species  originally  from 
southern  New  Mexico,  and  which  here  it  may  be  assumed, 
reaches  its  northern  limit  of  distribution.  Among  such  as 
these  were  also  gathered  a  few  herbaceous  plants,  notably 
Carex  aurea  and  Collomia  lanceolata,  and  several  more,  which 
are  more  properly  subalpine  and  alpine.  And  as  we  after- 
wards grew  familiar  with  the  whole  region,  including  the 
higher  elevations  about  the  headwaters  of  this  stream  less 
than  twenty  miles  away,  the  wonder  constantly  grew,  not 
that  only  a  few  alpine  or  subalpine  plants  should  occur  in 
the  valley  below,  but  that  so  few  of  these  species  had  been 
able  to  adapt  themselves  to  the  condition  of  the  lower  levels 
even  where  the  cool  thickets  furnished  such  excellent  shade 
with  abundant  moisture,  and  the  rapidly  flowing  stream 
offered  such  abundant  facilities  for  the  downward  distribution 
of  seeds.  As  a  rule  the  Mancos  specimens  of  species  having 
a  considerable  altitudinal  distribution  were  taller  and  more 
slender  than  those  subsequently  taken  in  mountain  mea- 
dows ;  which  variation  seems  attributable  partly,  at  least,  to 
their  having  grown  in  the  shade.  But  in  other  cases,  such 
as  the  Collomia  and  Carex  aureo,,  the  low  elevation  seemed 
to  have  had  the  opposite  effect  of  dwarfing  the  plants ;  speci- 
mens from  about  Mancos  being  much  smaller  than  those 
taken  at  elevations  greater  by  a  thousand  feet. 

Separated  from  the  flood-plain  by  a  steep  bank  five  to  fif- 
teen or  even  twenty  feet  high,  and  constituting  a  more 
elevated  secondary  bottom,  the  sage  plain  stretches  away 
for  a  mile  or  more  on  either  side  of  the  valley  to  the  foot-

hills.  This  tract,  as  I  have  said,  has  in  part  been  reclaimed 
and  brought  under  cultivation.  Originally  it  was  covered 
with  low-growing  gray-green  chenopodiaceous  and  composite 
shrubs,  such  as  constitute  what  is  commonly  called  sage 
brush.  Those  portions  not  under  cultivation  exhibit  these 
growths,  intermixed  with  clumps  of  bushy  Amelanchier  and 
Peraphyllum  representing  the  family  of  the  Pomacese;  and 
it  also  supports  a  peculiar  and  most  interesting  herbaceous 
flora,  made  up  of  Lupinus  argenteus  and  other  lupines, 
numerous  species  of  Astragalus  and  other  papilionaceas, 
several  Pentstemons  and  Castilleias,  Allium  acuminatum 
and  Calochortus  Gunnisonii  representing  the  lily  family. 

The  pinon  belt  occupies  the  low  foothills  from  100  to  400 
or  500  feet  above  the  valley.  Here  Pinus  edulis  and  Juni- 
perus  monosperma  combine  in  not  unequal  proportions  to 
form  a  low  scraggy  woodland  growth.  Neither  species  often 
exceeds  twenty  feet  in  height,  and  each  is  frequently 
adorned  by  its  own  species  of  parasitic  Razoumoffskia  and 
Phoradmdron.  Herbage  is  scanty  in  this  belt,  and  the  her- 
baceous species  quite  characteristic,  like  Lescuriella  Palmeri, 
Pentstemon  linarioides,  Astragalus  scopulorum  and  Picradenia 
Richardsonii. 

Our  belated  Mississippian,  Professor  Tracy,  arrived  in  the 
morning  of  June  26  and  we  started  at  once  for  the  western 
flank  of  Mi  Hesperus,  our  wagon  piled  high  with  boxes  of 
paper,  presses,  bundles  of  driers  and  camp  equipage.  Our 
plan  was  to  make  a  somewhat  permanent  camp  as  near 
timber  line  as  we  could  go  with  a  wagon,  and  then  to  take 
time  to  thoroughly  explore  the  country  both  above  and 
below.  Our  road  started  due  north  from  Mancos  but  soon 
bore  northeast  and  followed  up  a  rather  narrow  ridge  or 
divide  between  the  deep  rocky  canon  of  the  West  Mancos 
on  the  right,  and  Chicken  Creek,  a  smaller  tributary  of  the 


6  PLANTS    BAKERIAN^E. 

Mancos,  on  the  left.  About  four  miles  from  town,  and  at 
an  elevation  of  some  7,500  feet,  we  left  the  pifions  and  the 
chaparral-covered  hillsides  through  which  we  had  been 
traveling,  and  came  suddenly  into  magnificent  open  pine 
woods.  Our  driver  told  us  that  the  lumbermen  distin- 
guished two  kinds  of  pine,  but  all  seemed  to  be  Pinus  sco- 
pulorum  the  difference  in  the  timber  being  probably  due  to 
differences  in  the  age  and  condition  of  the  trees.  Many  of 
the  pines  are  of  large  size  and  the  ground  between  them, 
while  mostly  clear  of  brushwood,  yields  a  sufficient  growth 
of  grass  and  herbage  to  give  it  an  attractive  park-like  effect. 
Though  the  collecting  in  this  lower  part  of  the  pine  belt 
was  not  specially  interesting,  it  furnished  a  few  charac- 
teristic plants,  such  as  Lotus  Wrightii  and  Lithospermum 
multiflorum. 

Advancing  toward  higher  ground,  the  winding  road 
brought  us  to  an  elevation  of  about  9,000  feet,  where  the 
pines  give  place  to  aspen  thickets.  At  this  point  we  ob- 
tained our  first  impression  of  the  riches  of  vegetation 
belonging  to  the  higher  mountains;  for  the  aspen  thickets 
of  limited  extent  were  found  to  alternate  with  considerable 
stretches  of  native  meadow  brilliant  with  a  great  diversity  of 
flowers  blooming  among  the  abundant  grasses.  Fields  of 
the  large  sunflower-like  JFye£/mi  Arizonica,  clumps  of  purple 
lupine  bordering  these,  red  Castilleias  and  white  Polygonum 
bistortoides,  Potentillas  of  several  sorts  along  with  other 
things  as  show}'  combined  to  form  a  beautiful  and  most 
inviting  botanical  landscape. 

Still  continuing  the  gradual  ascent,  spruces  (Picea  Engel- 
mannii)  began  to  intersperse  themselves  in  groups  among 
the  aspen  clumps,  becoming  gradually  more  and  more  pre- 
ponderant, until  finally  the  aspens  cease  altogether  at  11.000 
eet,  where  the  spruces  thenceforward  hold  undisputed  sway

up  to  the  timber-line  which,  in  this  latitude,  is  at  about 
11,500  feet. 

Having  made  a  late  start,  on  this  first  day  of  the  ascent, 
we  covered  only  about  fifteen  miles,  camping  for  the  night 
near  the  head  of  Chicken  Creek.  A  little  beyond  this  point 
our  road  descended  abruptly  into  the  West  Mancos  Canon, 
thence  following  that  stream  up  to  Jackson's  stamp  mill, 
at  the  very  base  of  Mt.  Hesperus.  The  difficulty  of  getting 
our  heavy  outfit  back  out  of  this  deep  canon  seemed  so 
great  that  we  decided  to  keep  on  up  the  ridge,  following 
some  old  cattle  and  pack  trails  as  far  as  it  should  prove 
practicable  to  take  the  wagon.  We  succeeded  in  getting 
three  or  four  miles  further,  and  made  our  second  camp  on 
the  headwaters  of  a  little  tributary  of  the  West  Mancos 
locally  known  as  Bob  Creek.  We  had  reached  an  elevation 
of  10,500  feet  and  were  about  two  and  a  half  miles  due  west 
of  the  main  peak  of  Mt.  Hesperus,  but  with  the  deep  and 
rugged  valley  of  Slide  Rock  Creek  lying  between.  The 
laborious  climb  out  of  this  valley  with  a  heavy  load  of 
plants,  after  a  day's  collecting  on  Hesperus  convinced  us 
that  we  had  made  a  mistake  in  not  taking  the  lower  road 
and  so  pitching  our  camp  in  the  canon,  when  the  home- 
ward trip  would  always  have  been  down  hill. 

The  region  above  timber  was  reached  in  three  different 
places  from  this  Bob  Creek  camp,  on  the  southwest  face  of 
the  ridge  between  West  Mancos  and  Slide  Rock  Creeks, 
which  constitutes  the  westernmost  spur  of  Mt.  Hesperus,  on 
the  north  face  of  the  same  ridge  farther  east  near  the  head 
of  Slide  Rock  Creek,  and  on  the  Bear  Creek  divide  north- 
east of  camp.  In  all  these  places  the  ground  was  rather 
dry  and  exposed.  Many  interesting  plants  were  taken,  but 
the  full  glory  of  the  alpine  vegetation  was  not  seen  till  we 


8  PLANTS    BAKERIAN.E. 

reached  the  moister  basins  at  the  head  of  the  La  Plata 
River  on  the  eastern  side  of  the  range. 

One  of  the  most  interesting  features  of  this  western  flank 
of  the  range  was  the  great  reaches  of  verdant  mountain 
meadow  stretching  away  in  every  direction  between  the 
scattered  clumps  of  spruces  and  aspens.  The  grass,  con- 
sisting largely  of  Poas  and  Festucas,  was  exceedingly 
luxuriant  and  was  everywhere  sprinkled  or  crowded  by 
showy  species  of  Mertensia,  Polemonium,  Valerianella, 
Frasera,  Veratrum,  Aconitum,  Delphinium  and  numberless 
other  smaller  flowering  plants. 

The  morning  of  July  6  found  us  breaking  camp  and 
starting  on  the  return  trip  to  Mancos.  The  season  was  now 
at  its  height,  and  it  was  marvelous  to  see  how  rapidly  vege- 
tation was  developing  at  these  high  altitudes.  Had  time 
permitted  we  should  gladly  have  lingered  longer  at  this 
camp,  for  each  day  brought  new  species  into  bloom,  and  it 
seemed  to  our  regretful  eyes  that  we  were  leaving  more  still 
undeveloped  species  behind  us  than  we  had  found  in  con- 
dition to  collect.  The  trip  back  to  Mancos  occupied  two 
days,  as  much  time  was  consumed  in  collecting  on  the  way 
the  things  that  had  opened  during  our  brief  absence.  A 
further  stop  of  two  days  in  Mancos  enabled  us  to  pack  and 
ship  the  dried  plants  that  had  accumulated,  and  to  take  a 
short  side  trip  over  the  sage  plains  to  the  south  westward  along 
the  road  toward  Cortez,  in  the  direction  of  the  Ute  Moun- 
tain. This  day's  collecting  proved  to  be  the  richest  in  the 
number  of  specimens  taken  and  in  the  number  of  new 
species  of  flowering  plants  discovered  of  any  on  the  entire 
trip,  thus  showing  that  in  planning  future  work  in  this 
region  the  lower  levels  should  receive  careful  attention. 

The  afternoon  of  July  9  found  us  again  under  way  for 
a  trip  up  the  La  Plata  Valley  on  the  east  side  of  Mt. 


NARRATIVE.  9 

Hesperus.  Our  route  lay  over  some  low  divides  through  a 
rather  uninteresting  country,  part  of  the  time  in  oak 
chaparral,  and  at  times  getting  up  into  the  open  pine  belt. 
During  the  afternoon  of  July  10  we  passed  Dix  P.  O. 
and  reached  the  old  mining  camp  of  Parrott  City  at  the 
foot  of  the  mountains,  just  at  the  entrance  to  the  canon 
of  the  La  Plata  River.  Continuing  a  few  miles  further,  we 
made  camp  in  the  bottom  of  the  canon  about  two  miles 
south  of  La  Plata  City.  This  was  one  of  the  richest  spots 
visited.  The  bottom  of  the  valley  is  only  a  few  hundred 
yards  wide,  and  it  is  walled  in  on  either  side  by  the  pre- 
cipitous slopes  of  the  mountains.  It  is  very  moist,  and  is 
filled  with  a  luxuriant  tangle  of  vegetation.  Rubus  Nutkanus 
here  grows  to  perfection,  and  the  ground  is  fairly  carpeted 
with  the  showy  Erigeron  coulteri  and  Penstemon  glaucus 
stenosepalus.  The  gravel  banks  in  the  stream  also  furnished 
conspicuous  and  abundant  species,  including  Epilobium 
latifolium  and  Senecio  atratus.  The  elevation  here  was  about 
9,000  feet. 

On  July  12  we  again  moved  camp  going  toward  the  head 
of  the  valley.  Above  the  town  of  La  Plata  the  canon  grows 
much  narrower  and  the  grade  is  much  steeper.  The  road  is 
soon  forced  to  leave  the  stream  and  is  cut  into  the  hillside. 
For  a  considerable  distance  no  suitable  place  for  a  carnp 
could  be  found,  but  finally  just  below  the  mouth  of  Basin 
Creek,  at  about  10,000  feet  elevation,  a  projecting  ledge  of 
rock  gave  us  just  room  to  put  up  the  tent  and  get  the  wagon 
out  of  the  road.  Stakes  being  out  of  the  question  tent  ropes 
were  made  fast  to  boulders,  and  our  quarters,  though  re- 
stricted, proved  sufficiently  comfortable.  Wagon  roads  have 
been  constructed  several  miles  farther  to  reach  various 
stamp  mills,  but  they  were  so  rough  and  steep  that  we 
did  not  attempt  to  take  our  heavy  outfit  beyond  this 


10  PLANTS    BAKERIAN.E. 

point  but  made  daily  trips  above  timber  line  in  various 
directions. 

The  basins  of  the  small  streams  far  above  timber  line 
were  here  all  veritable  alpine  gardens  well  stocked  with 
Mertensias,  Polemoniums,  Trifoliums,  Erigerons,  Castilleias 
and  many  other  showy  alpine  genera.  Even  the  most 
rugged  slopes  exhibited  a  great  diversity  of  species ;  for 
every  nook  and  crevice  among  the  rocks  where  any  soil  had 
found  a  lodgment  was  filled  with  plants.  On  the  very 
summit  of  Ml  Hayden  at  13,000  feet  we  gathered  excel- 
lent specimens  of  Trifolium  nanum,  Chionophila  Jamesii, 
Ligusticum  Eastwoodiae  and  Pentstemon  Harbourii. 

It  is  to  be  noted  that  about  three-fourths  of  the  plants 
collected  here  were  of  species  not  represented  at  any  of  the 
lower  altitudes. 

It  was  with  much  regret  that  on  July  16  we  took  leave 
of  this  interesting  locality  and  made  our  way  to  Durango. 
Each  little  sheltered  slope  and  basin  that  we  visited  fur- 
nished some  plant  not  seen  elsewhere,  and,  had  time  per- 
mitted a  thorough  exploration  of  the  region  our  list  of 
species  would  have  received  many  additions.  Furthermore, 
the  flowering  season  had  not  yet  reached  its  fullness.  Very 
many  species  were  not  yet  beginning  to  bloom,  and  it  was 
manifest  that  a  month's  sojourn  would  have  enabled  us  to 
nearly  double  our  collections. 

This  Alpine  research  was  disappointing  in  respect  to  only 
two  groups  of  plants.  Of  ferns  we  took  but  two  species, 
Cystopteris  fragilis  and  Oryptogramme  acrostichoides ;  and  the 
number  of  lichens  was  much  smaller  than  had  been  antici- 
pated. The  bare  rocks  supported  a  fair  number  of  crusta- 
ceous  species,  which,  owing  to  the  early  loss  of  our  chisel, 
we  were  unable  to  collect ;  and  terrestrial  and  arboreal 
species  were  very  scarce. 


NARRATIVE.  11 

Durango  is  a  thriving  town  located  in  the  valley  of  the 
Las  Animas  river  at  an  elevation  of  6,500  feet.  South  of  the 
town  the  hills  rise  1,000  or  1,500  feet  higher.  They  are 
mostly  composed  of  beds  of  shale  with  a  few  coal-bearing 
strata  and  so  give  but  few  plants  of  interest  during  the  hot 
midsummer  months,  even  along  the  narrow  ravines  and 
arroyas.  The  Grindelias,  Mentzelias  and  Eriogonums 
found  within  the  city  limits  proved  fully  as  interesting  as 
the  plants  of  these  nearby  hills.  In  some  places  they  sup- 
port a  considerable  growth  of  Juniperus  monosperma  with 
scattered  trees  of  pinon.  Near  the  eastern  edge  of  the 
town  one  small  hill  was  noticed  that  had  been  covered  by  a 
rather  dense  growth  of  this  juniper,  but  now  only  a  few  of 
the  trees  were  living,  the  others  having  apparently  been 
killed  by  Gymnosporangium  speciosum  Peck,  which  had  left 
the  swollen  and  distorted  trunks  marked  with  its  peculiar 
plicate  tumors. 

North  of  town  toward  Trimble  Springs  the  Animas  valley 
is  somewhat  broader,  though  bounded  on  each  side  by  pre- 
cipitous mountain  walls  which  rise  from  2,000  to  2,500  feet 
above  the  stream.  Every  acre  of  irrigable  land  is  in  a  high 
state  of  cultivation,  hay  or  green  fields  and  orchards  filling 
all  the  valley  from  Durango  to  where  the  Hermosa  River 
joins  the  Animas.  Here  we  noted  similar  willows  to  those 
found  at  Mancos  and  at  the  base  of  the  cliffs  were  box  elders 
and  Ribes  cereum. 

Through  the  kindness  of  Col.  Thomas  Hamor,  of  Durango, 
we  were  enabled  to  make  a  somewhat  hasty  trip  to  Colum- 
bine, twenty-five  miles  north  of  Durango,  on  the  old  Silverton 
trail,  and  only  a  few  miles  to  the  eastward  of  our  Upper 
La  Plata  camp.  The  place  is  near  the  head  of  the  valley, 
and  Hamor's  Lake,  a  picturesquely  beautiful  sheet  of  water, 
is  one  of  the  sources  of  the  Las  Animas  river.  The  lake 


12  PLANTS    BAKERIAN.E. 

seems  to  have  been  formed  by  the  sudden  closing  in  of  the 
canon  wall  so  that  though  not  large  it  is  of  great  depth.  It 
is  as  clear  as  crystal  and  even  after  our  visit  it  still  contains 
some  magnificent  trout.  The  elevation  here  is  about  9,000 
feet  and  the  hills  and  wet  meadows  near  the  lake  yielded  a 
greater  number  of  species  than  any  other  equal  area  that 
we  visited.  In  the  water  of  the  lake  itself  was  an  abun- 
dance of  Chara  Hippuris  and  Potamogeton  while  on  its 
borders  were  Thalictrum  alpinum,Gentiana  heterosepala,Swertia 
scopulina,  Agastache  urticsefolia,  Lilium  montanum  and  many 
other  species  not  taken  elsewhere. 

Mr.  Tracy,  who  was  the  last  to  arrive,  remained  in  the 
neighborhood  of  Durango  until  July  28.  Messrs.  Earle 
and  Baker  departed  on  the  18th  and  19th  respectively, 
making  about  an  even  month  in  the  field  for  each  of  the 
three  members  of  the  expedition. 

Perhaps  the  most  striking  impression  gained  by  the  trip, 
aside  from  that  produced  by  the  abundance  and  beauty  of 
the  high  alpine  flora,  is  that  of  the  distinctness  with  which 
the  different  altitudinal  floral  zones  are  marked  out  and 
limited.  It  is  true  a  few  species  were  found  all  the  way 
from  the  Mancos  River  bottoms  at  7,000  feet  to  timber  line 
at  11,500  feet,  but  these  instances  are  rare.  In  the  great 
majority  of  cases  each  species  observed  had  an  altitudinal 
range  of  not  to  exceed  1,000  feet,  even  with  similar  con- 
ditions of  soil  and  moisture.  In  a  general  way  these  life 
zones  seemed  to  be  the  same  here  as  in  the  not  far  distant 
San  Francisco  Mountains  of  Arizona,  where  they  have  been 
so  carefully  studied  by  Dr.  Merriam,  of  the  U.  S.  Biological 
Survey.  We  could  easilv  distinguish  the  pinon-cedar  belt, 
the  pine  belt,  the  aspen-spruce  belt  and  the  timber  line  belt 
as  designated  by  him,  and  we  found  this  division  a  very 
useful  one  in  the  prosecution  of  our  work. 


NARRATIVE.  13 

While  we  endeavored  to  make  our  work  as  thorough  as 
possible  for  the  very  limited  region  actually  explored,  we 
realize  fully  that  it  is  only  a  beginning.  The  number  of 
plants  collected  serves  to  illustrate  the  great  floral  richness 
of  the  region,  and  our  experience  suggests  that  for  future 
work  the  higher  mountains  should  be  visited  during  the 
period  from  July  15  to  September  1,  when  an  almost 
entirely  new  set  of  plants  would  be  in  bloom;  and  that 
work  in  the  lower  levels,  especially  in  the  canon  and  mesa 
region  south  and  west  of  Mancos  is  greatly  needed  earlier 
in  the  season,  say  from  May  1  to  June  15.  It  is  hoped 
that  at  least  some  of  our  party  may  be  able  to  continue  the 
work  another  season.

Among  the  more  striking  features  of  the  fungus  flora  of 
the  region  which  the  collection  represents  may  be  men- 
tioned the  great  abundance  of  the  Uredinales  and  Sphserlales. 
The  Erysibacese  would  have  been  abundant  later  in  the 
season,  though  only  two  species  were  found  in  condition  to 
collect.  Perisporacese  were  entirely  lacking,  as  were  also  the 
Hysteriales,  though  the  latter  were  persistently  sought  for 
everywhere.  The  Pezizales  are  represented  by  only  two 
species.  The  Helvellales  do  not  appear  in  the  list,  but  fine 
specimens  of  Morchella  and  Gyromitra  were  observed  in  the 
high  spruce  woods.  The  Agaricacese  are  very  scantily  rep- 
resented in  the  list,  but  they  were  really  quite  abundant  in 
moist  locations  at  the  higher  altitudes.  Lack  of  time  and 
of  facilities  for  properly  drying  the  specimens  prevented 
collecting  them.  Among  the  Sphseriales  which  constitute 
nearly  a  third  of  all  the  species  collected,  and  of  which  con- 
siderably over  one-half  proved  to  be  undescribed,  the  almost 
entire  absence  of  such  common  eastern  genera  as  Hypoxylon 
and  Valsa  is  to  be  noted,  as  well  as  the  great  abundance  of 
Lopliiostomatacese,  a  family  rarely  found  by  eastern  col- 
lectors. The  Dothideales  and  Hypocreales  are  each  repre- 
sented by  a  single  species  only. 

It  is  interesting  to  note  that  of  the  entire  collection  only 
the  following  five  species  were  taken  above  timber  line: 
Schizonella  melogramma,  Puccinia  acrophila,  P.  Claytoniatum, 
P.  Pimpinellas  and  Patinella  Crandallii.  The  smallness  of  this 
list  is  to  be  accounted  for  in  great  part  by  the  fact  that  our

time  above  timber  line  was  always  limited  and  that  the 
beauty  and  abundance  of  the  flowering  plants  claimed  our 
attention,  to  the  neglect  of  the  Fungi. 

In  the  following  list  the  sequence  of  families  is  that  of 
Engler  &  Prantl.  In  the  few  cases  in  which  the  generic 
name  used  by  us  is  another  than  that  employed  by  Saccardo 
in  the  Sylloge  Fungorum,  the  latter  is  added  in  parenthesis.

This  has  not  before  been  reported  from  America.  The 
asci  soon  vanish,  and  at  full  maturity  the  ascospores  are 
fuliginous.  In  our  specimens  the  perithecia  often  reach 
5mm.  In  other  respects  it  closely  agrees  with  the  descrip- 
tion given  by  Hartig.  It  was  also  observed  on  Mt.  Hes- 
perus near  timber  line,  but  was  not  seen  below  11,000  feet. 
This  was  previously  collected  by  C.  F.  Baker  on  spruce  in 
northern  Colorado,  July  13,  1896,  at  Cameron  Pass,  10,000 
feet,  and  distributed  by  him  under  the  name  of  Lasiosphseria 
Coulteri,  Peck.  It  closely  resembles  that  pine-inhabiting 
species  externally,  but  the  spores  are  entirely  different.

On  dead  twigs  of  Symphoricarpus,  Bob  Creek,  10,500  feet, 
June  27,  n.  173,  with  Rosellinia  parasitica  and  Strickeria  Sym- 
phoricarpi.  The  true  generic  position  of  this  species  is 
somewhat  doubtful.  Its  scanty  imperfect  stroma  suggests 
that  it  should  be  placed  in  the  CucurbitariaceaB  rather  than 
in  Mellogramma,  but  the  vestiture  of  the  perithecia  would 
exclude  it  from  Gibberidia,  as  that  genus  is  now  denned. 
Since  perithecial  hairs  are  present  in  the  nearly  related 
Gibbera,  from  which  our  species  is  excluded  by  the  spore 
characters,  we  prefer  to  widen  the  definition  of  Gibberidia 
rather  than  to  propose  a  new  genus  based  only  on  the  pres- 
ence of  perithecial  hairs.
